ACH of the ten groups of linked genes in maize has been associated E with a specific member of the haploid set of ten chromosomes. The morphology of the ten chromsomes has been studied a t pachytene by MCCLINTOCK (1933) and each member found to differ from the others in such characters as length, position of the spindle fiber insertion region and presence of deeply staining knobs in definite po...

RISOMIC inheritance was first reported in maize by MCCLINTOCK (1929) T in a study of segregating progenies derived from a spontaneous triploid (RANDOLPH and MCCLINTOCK 1926). Later MCCLINTOCK and HILL (1931) identified the primary trisome of chromosome IO, the shortest member of the maize chromosome complement which carries the r-g linkage group, and certain general observations on the known pr...

The regulation of protein synthesis in the pigeon has been studied by comparing the capability of cell-free amino acid incorporating systems of membrane-bound and membrane-free polysomes prepared from fasted and fed birds. New methods were developed for isolating polysomes since techniques used for other tissues did not provide quantitative recovery of polysomal RNA. The sucrose gradient profil...
متن کاملCharacterization of a Putative Spindle Assembly Checkpoint Kinase Mps1, Suggests Its Involvement in Cell Division, Morphogenesis and Oxidative Stress Tolerance in Candida albicans
In Saccharomyces cerevisiae MPS1 is one of the major protein kinase that governs the spindle checkpoint pathway. The S. cerevisiae structural homolog of opportunistic pathogen Candida albicans CaMPS1, is indispensable for the cell viability. The essentiality of Mps1 was confirmed by Homozygote Trisome test. To determine its biological function in this pathogen conditional mutant was generated t...
